Hello All Looking for help to identify this brass-back tenon saw. Nearest I can get to it is 'drabble and sanderson', but, the top two buttons on this saw appear on a parrallel line whereas on the D&S the righthand one appears lower. No markings at all on the brass. I fancy there was some etching on the pitted blade but that has long gone. Look forward to some good guesses. Cheers. Pat
